GWG-1000-1A1

The "BAR" value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked "200m" have the same water resistance as 20 BAR watches.

Smart Access

This ground-breaking CASIO system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown.

Tough Movement

TOUGH MOVEMENT is a CASIO-original thin analog movement that is packed with a host of amazing features and functions. A MULTIBAND 6 function makes it possible for the watch to receive calibration signals for Japan (two signals), China, the United States, England, and Germany, for true international timekeeping. Movement durability and integrity are ensured by hybrid mount construction to protect against damage and by auto hand home position correction to keep settings accurate. A Tough Solar power system generates power from even small amounts of fl uorescent lighting and stores it in a secondary battery to help keep power-hungry functions running. The result is a totally new thin analog radio-controlled solar movement that embodies some of the very best technology that CASIO has to offer.

Tough Solar

CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.

Radio-controlled Watch; Multi band 6
